What advice would you give to young women entering your industry?
The advice I would give to young women entering my industry is to stay true to yourself and trust your instincts. There are many paths to success, but it is essential not to compromise your values along the way. Focus on earning your achievements through hard work, consistency, and integrity, and be cautious of shortcuts or “fast-track” options that may undermine your long-term credibility and growth.
What are the biggest challenges or opportunities in your field right now?
One of the biggest challenges in my field is navigating and advancing within a traditionally male-dominated industry. While progress has been made, there remains a need to continually demonstrate expertise, assert leadership, and advocate for equitable opportunities. At the same time, this challenge presents an opportunity to contribute to meaningful change by fostering inclusion, mentoring others, and helping shape a more diverse and balanced professional environment.
What values are most important to you in your work and personal life?
The values most important to me in both my work and personal life are integrity, loyalty, and building up others. I strive to conduct myself with honesty and strong ethical principles, remain steadfast and dependable in my commitments, and intentionally support, encourage, and empower those around me to grow and succeed.
